There was stress reaction -4000 kcal per cycle. When I notice label "starvation" she has 16 kcal, and I was pretty sure that's it. But she take surf'n'turf from nowhere (I did not understand where it was located), and amount of calories grow to 460. Then she walk a little, calories fall down to 300, stress fall down from 100 to 60, she pee in pants and die from starvation (or shame).
have no idea. Call hunger stress reaction, give food. May be it happen because I have pretty large colony and my PC just can't complete all computations in a time. I can provide savefile if needed.
